Crypto miners that are secretly embedded into websites have become a big concern for smartphone users.  Just recently, a serious Trojan malware program designed to mine for cryptocurrency caused a person’s phone to work so hard that the battery blew open the phone’s back cover.

Luckily, one company is providing a solution with its latest web browser offering. The Opera web browser, developed by Otello Corporation, has already been providing cryptocurrency miner security in its desktop-based versions, and will now be offering the same feature in its smartphone browsers, according to the company.

According to information shared in a recent press release, this new feature is currently available on Opera for Android and Opera Mini, and is a part of the browser’s native ad-blocker function.

The press release states, “The new anti-cryptocurrency mining feature is activated by default when you enable the ad blocker on Opera Mini (iOS and Android) or Opera for Android. The ad blocker can be enabled by going to ‘settings’, and it will automatically detect and stop the mining scripts written into the code of a webpage.”

The company says that over a billion devices globally are hampered by website-based cryptocurrency miners that users don’t even realize are hijacking their browers.  To top it off, the company states there are currently over 3 million websites secretly embedded with digital currency miners.

One of the major problems with these malware programs is that they don’t present any visual cues that they are there, unless they overload a smartphone’s CPUs, causing overheating in a phone, or blowing up the battery. These aggressive malware miners can damage a phone beyond repair within 48 hours.

According to the press release, Opera’s new feature is already available for use, and the browser can be downloaded from the Google Play store.  With this browser in place, the threat from mining malware will hopefully be eliminated.
